Azimuth angle question


Dear all,

I have a question regarding the solar azimuth parameter, which is defined as:
The angle between a line pointing due north to the sun’s current position in the sky. Negative to the East. Positive to the West. 0 at due North. (
So does my interpretation shown in the attached picture below correct?
Thank you!

Hi Fadhil,

That is correct, this I believe largely comes from the fact that Solcast is an Australian based company and the research done used equations with these values of negative for East and positive for West.
